To ensure optimal project management and efficient execution, I meticulously assembled a high-performing team of four professionals who exemplified their expertise. By adopting the Kanban methodology and prioritizing constant communication with the client, we fostered a collaborative environment that supported timely decision-making and feedback integration. The outcome was a cutting-edge platform that streamlined the engraving design process and significantly enhanced user satisfaction, paving the way for new opportunities in the B2B market.
